good evening!
I would like to better understand this project, if it is compatible with Harbor and consequently with the HMG of Roberto Lopez and, if also for smartphone?
because we need to modernize our language and create small applications for android and interact with our bigger application that is for computer.

IMHO the easiest way is to develop a WebApp by making a bridge between the native java of Android and javascript, then it is compiled with the SDK (that make the apk). The graphic interface is made with HTML5, jQuery Mobile, etc. and the access to hardware and resources (storage card, camera, sensors, SQLittle, etc) write in java. Then you directly call the functions written in java from the javascript code. I have some personal applications developed in that way.
